Description

Technical Field

[0001] The utility model relates to the technical field of rotary anode furnaces, in particular to a rotary anode furnace tuyere masonry structure. Background Art

[0002] The rotary anode furnace is a key equipment for pyrometallurgical refining of crude copper. A series of operations such as heating, oxidation, and reduction of crude copper are all completed in the rotary furnace, among which oxidation and reduction are the most important operating steps in crude copper refining. During the oxidation and reduction operations, it is necessary to manually wrap a steel pipe with mud and insert it directly into the copper liquid from the tuyere, and blow compressed air and pulverized coal reducing agent into the copper liquid to complete the oxidation and reduction operations. Specifically, during the oxidation operation, a large amount of air needs to be blown in from the tuyere, and the tuyere bricks have to withstand the erosion of rapid airflow during this process; during the reduction stage, the reducing agent needs to be sprayed into the furnace from the tuyere, and the tuyere bricks have to withstand the turbulence and mechanical stress caused by the spraying of the reducing agent, which causes serious damage to the structure at the tuyere.

[0003] The traditional tuyere structure is generally formed by splicing multiple tuyere bricks or built by a thickened tuyere brick. However, the tuyere structure formed by splicing multiple tuyere bricks is not strong enough, and the gaps between bricks are difficult to control. After the tuyere bricks are burned and shortened, the melt can easily penetrate outward from the gaps and burn the furnace shell. The service life is short and the tuyere bricks may fall off in severe cases. For the tuyere structure built by a thickened tuyere brick, the part extending out of the peripheral length of the furnace body is more susceptible to melt erosion and wears out faster, which fails to achieve the purpose of extending the service life of the tuyere. Utility Model Content

[0004] The utility model aims to provide a rotary anode furnace tuyere masonry structure to solve the above technical problems, effectively alleviate the scouring and erosion of the melt, and extend the service life.

[0005] The embodiment of the utility model is realized through the following technical scheme: a rotary anode furnace tuyere masonry structure, including a cylindrical furnace shell, the inner wall of the furnace shell is masonry with furnace body bricks, the side wall of the furnace shell is provided with tuyere, the inner wall of the furnace shell is fitted with fan-shaped bricks, the fan-shaped bricks are provided with through holes inclined downward and connected to the tuyere, the length of the fan-shaped bricks along the radial direction of the furnace shell is greater than the length of the furnace body bricks along the radial direction of the furnace shell, and processed bricks for gradual and smooth transition are masonry between the fan-shaped bricks and the furnace body bricks.

[0006] Furthermore, the processed bricks are laid with staggered joints up and down and left and right.

[0007] Furthermore, a guard plate is installed on the outer wall of the furnace shell, and a through hole communicating with the air port and the through hole is opened on the guard plate.

[0008] Preferably, the through hole is located in the center of the guard plate.

[0009] Furthermore, adhesive layers are provided between the processed bricks, between the processed bricks and the fan-shaped bricks, and between the processed bricks and the furnace body bricks.
